If you think it's important to maintain this library, please submit an issue and the case will be consider or the repo / ownership will be transferred to you. Viable alternatives:\n\n1. Use Browserify\n2. https://www.npmjs.com/package/sha.js (used by Browserify)\n3. https://github.com/indutny/hash.js\n\n\n## Install\n\n### Node.js/Browserify\n\n    npm install --save sha256\n\nNote: when Node.js is detected, the Node [`Crypto`](http://nodejs.org/api/crypto.html) component is used instead of re-implementing the SHA256 hash logic.\n\n\n\n## Usage\n\nThere are two methods, one for computing the hash of the input, and one for double-hashing it:\n\n```js\nsha256('hello');   // \"2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824\"\nsha256.x2('hello'); // \"d7914fe546b684688bb95f4f888a92dfc680603a75f23eb823658031fff766d9\"\n```\n\nInput is either an array of bytes or a string. **String are always interpreted as binary data**; if you have a hex-encoded string of data to parse, first convert it to a binary string or array of bytes.\n\nOutput by default is a hexadecimal-encoded string. Other options are an array of bytes, or a binary-encoded string:\n\n```js\nsha256('hello');   // \"2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824\" \u003c= Hex-encoded; default\nsha256('hello', { asBytes: true }); // [44,242,77,186,95,176,163,14,38,232,59,42,197,185,226,158,27,22,30,92,31,167,66,94,115,4,51,98,147,139,152,36] \u003c= Array of bytes\nsha256('hello', { asString: true }); // \",òMº_°£\u0026è;*Źâž\\§B^s3b“‹˜$\" \u003c= Binary-encoded string\n```\n\n## Test\n\nUnit tests are written in [Mocha](https://mochajs.org/). To run the test suite, checkout the git repository, and from within the base folder run:\n\n```sh\n$ npm install --dev\n$ npm test\n```\n\n# Credits\n\nMost of the code from CryptoJS https://code.google.com/p/crypto-js/\n\n# License\n\n(MIT License)\n\nCopyright 2013, JP Richardson  \u003cjprichardson@gmail.com\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcryptocoinjs%2Fsha256","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcryptocoinjs%2Fsha256","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcryptocoinjs%2Fsha256/lists"}
